Depay used to be someone who was cocky, cares a lot about money and loves to show off. He was a problematic youngster and plays selfishly. He also had some family problems and even removed "Depay" from the back of his shirt because he don't want to be called his father's name. His grandfather, who meant a lot to him, passed away as well, and he was a confused kid. However, everything had changed dramatically ever since LVG brought him into the national team.
Since then, he had gotten over his problems, and I am sure LVG plays a big part in it. He starts playing for the team more and does his defense duties as well. Not exceptional in defending, but he is improving fast. He had became more of a team player who picks his moment to make things happen instead of dribbling into blind alleys. He only starts taking more risks when his team needs him to, and is more than willing to be disciplined if that is what's required of him. He no longer makes as many poor decisions as he was when he first debuted, and had matured massively in the past one and a half season. He is not exactly a speed demon (still very fast mind you, just not on Bale's level for example), and isn't as good in tight spaces as say Nani, but he can do a lot with space in front of him as he has good acceleration and doesn't get pushed off the ball easily. He is also a gym fanatic and loves working out a lot, which explains his strength on the ball.
PSV's got a gentlemen's agreement to sell him if the price is right and won't force him to the highest bidder. He favourited two tweets that links him to us and looking at his relationship with LVG, I think we will definitely get him as long as we want him. I believe he will only go to another club if we are not in for him. All of these were told by someone who watches PSV a lot.
